| Am I right in saying that there can ONLY be 43 EGs which can have SOAP nodes( for HTTP connection) in them per physical Server? |

You can change the range to make it bigger if you really need to 
Kind Regards,

By the Embedded HTTP Listener for SOAP Input nodes or HTTP Input nodes that use the embedded listener.

Oh, you mean the default setting for which there is a ton of documentation on how to change?
That?

One advanced topic that would need alot of discussion for your understanding is how a typical ESB system is configured.
In most instances, where WMB is performing the function of the ESB application, the other parts to the ESB system likely include WAS servers, Datapower appliances, and other components.
When there is a likelihood of heavy HTTP traffic in the ESB system, a design pattern that gets invoked alot is where the HTTP requests are front-ended by a device other than the ESB application (in this case WMB being the ESB application, and the front-end being serviced by WAS or a Datapower appliance).
So, for example, one use case is a WAS server receives the upstream HTTP request, does validation on the user authority, perhaps some payload enrichment, and then passes the transaction (usually via MQ at that point) to the ESB application (WMB).
The end result is that the ESB application (WMB) doesn't handle all that many HTTP requests directly. Most HTTP requests are front-ended by another system component, such as WAS.
One benefit to such an arrangement is division of scope and shared horsepower application, where the overall latency SLA is more reliably achieved and predictable.

@mqjeff , mgk - can you point me to one such docplease. Much appreciated.
@lancelotinc - thanks for the gyan. Though it was just a curious question not prompted by any of the integration designs/architecture patterns.
I just wanted to know if I read this article right?

My dissertation points out that very rarely will you use more than a few HTTP ports on WMB. This is because other components of the overall system are the primary HTTP interface, not the WMB product.
I did not say you couldn't or shouldn't. I said in a likely design, WAS and Datapower "front-end" the HTTP traffic allowing WMB to process richer payload. This is more ideal rather than having WMB handle the more mundane marshalling of SOAP requests. WAS and Datapower are more suited to this sort of stuff and WMB is better suited to be the high-speed messaging engine backbone.

Try this: http://www-01.ibm.com/support/docview.wss?uid=swg21420032
Notice how it has a number of sentences that say "as described here", and the word "here" is a URL?
No.
You did not read that article right.
That article tells you what the DEFAULT configuration is, and then provides LINKS TO DOCUMENTATION.
Notice also the sentence that says "All of these port numbers are completely user-configurable. " |

Got it!!
So i use -n explicitlySetPortNumber to change it to any value.
Thanks
